Description

Technical Field

[0001] This invention relates to a double-shielded composite device, and more particularly to a double-shielded composite device for processing protective glove sleeves, belonging to the field of protective glove sleeve processing technology. Background Technology

[0002] As core protective equipment in special fields such as medical, nuclear industry, and electronic chemical industry, the quality of the composite molding of the shielding layer of protective gloves directly determines the protective effectiveness. In order to meet the high-end protection needs, the double shielding layer composite process is currently used to prepare protective gloves. The composite of two shielding materials achieves dual protection against electromagnetic, ionizing radiation or chemical substances. Coating and high-pressure airless spraying are two of the most widely used processes in the composite molding of the shielding layer of existing protective gloves.

[0003] In existing technologies, if a coating process is used for the composite molding of the double shielding layer, the adhesive, due to its fluidity, is prone to problems such as dripping, localized accumulation, or uneven thickness on the irregularly shaped curved substrate of the protective glove sleeve. This directly leads to a shift in the protective area of ​​the shielding layer and insufficient effective protection, severely affecting the overall molding effect of the double shielding layer and failing to guarantee the consistency of shielding protection across different parts of the protective glove sleeve. While using a high-pressure airless sprayer for the coating process offers better uniformity than the coating process and effectively improves the problem of uneven shielding layer thickness, the existing spraying equipment... The head is mostly fixed. After the protective glove sleeve substrate is fixed on the mold and transported to the spraying station by the conveyor mechanism, it needs to stop at a fixed point. Then, a special electrical rotating mechanism is used to control the rotation of the mold to achieve all-round spraying of the curved surface of the protective glove sleeve. Only after the spraying is completed can it continue to flow to the next process by the conveyor mechanism. This method directly disrupts the continuous conveying of the protective glove sleeve processing, greatly reduces the overall processing efficiency of the double shielding layer, and the entire spraying process requires multiple sets of electrical equipment to cooperate to achieve positioning, stopping, and rotation, which complicates the overall structure of the equipment, makes the operation cumbersome, and has poor convenience of use.

[0004] To address this issue, a double-shielded composite device for processing protective glove sleeves was designed to optimize the aforementioned problems. Summary of the Invention

[0005] The main objective of this invention is to provide a double-shielded composite device for processing protective glove sleeves. Through the mechanical cooperation of a side plate on one side of the frame with a turntable and a limiting cylinder, the limiting cylinder drives the glove sleeve to rotate during continuous conveying with the conveyor belt, eliminating the need for fixed-point stops. Simultaneously, a follow-up mechanism consisting of a sliding groove on the side of the slider, a trapezoidal guide block, and a spring automatically drives the slider of the nozzle assembly to move synchronously as the mounting block moves past the slider with the conveyor belt. Furthermore, a reset mechanism consisting of a fixed column on the frame, an end plate, a second spring, and a damper ensures that the nozzle automatically and accurately resets after spraying, forming a closed-loop operation process of continuous conveying, follow-up spraying, and automatic reset. This completely solves the problem of traditional high-pressure airless spraying requiring... The system eliminates the problems of fixed-point stops and disruption of conveying continuity. Relying entirely on a mechanical structure without the need for multiple electrical control devices, it simplifies the equipment structure, reduces the probability of failure, improves operational convenience, and increases processing efficiency. The lifting mechanism, composed of a vertical groove on the top of the slider, a support rod, and positioning bolts, allows for precise adjustment of the spraying height of the nozzle, adapting to protective gloves and sleeves of different lengths. Combined with a translation mechanism consisting of a horizontal plate, guide groove, guide block, screw, and adjustment knob, the lateral spraying width of the nozzle can be flexibly adjusted to meet the processing needs of different diameters or curved surfaces.

[0038] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0039] Example 1

[0040] like Figures 1-9 As shown, this embodiment provides a double-shielded composite device for processing protective glove sleeves, including a frame 1. The frame 1 is provided with a conveyor belt 2 for conveying the protective glove sleeve substrate. Mounting blocks 5 are spaced apart on the conveyor belt 2. A turntable 6 is rotatably mounted on the top of the mounting blocks 5. A limiting cylinder 7 is fixed on the top of the turntable 6. A side plate 8 is fixed on one side of the frame 1. The side plate 8 cooperates with the turntable 6 to drive the turntable 6 to rotate the limiting cylinder 7.

[0041] Both ends of the other side of the frame 1 are provided with slide rails 9 extending along its length. Slider 10 is slidably connected to each slide rail 9. A nozzle 13 for spraying shielding material is provided on the top of each slider 10. A spraying machine 14 connected to the nozzle 13 is provided below the frame 1.

[0042] The slider 10 is provided with a follower mechanism on the side near the mounting block 5. The follower mechanism includes a groove 15 opened on the side wall of the slider 10, a trapezoidal guide block 16 slidably disposed in the groove 15, and a spring 17 whose two ends are respectively connected to the inner wall of the groove 15 and the trapezoidal guide block 16.

[0043] The frame 1 is provided with a reset mechanism, which includes a fixed column 18 fixed to the frame 1, an end plate 19 fixed to the end of the slide rail 9, a second spring 20 connected to the end plate 19 and the slider 10 at both ends respectively, and a damper 21 arranged in parallel with the second spring 20.

[0044] The top of the slider 10 is provided with a lifting mechanism 11 for adjusting the height of the nozzle 13, and the lifting mechanism 11 is provided with a translation mechanism 12 for adjusting the lateral position of the nozzle 13;

[0045] Heating chambers 3 are provided at both ends of the frame 1 near the fixed column 18. The heating chambers 3 are fitted on the outside of the conveyor belt 2. A hot air blower 4 is provided on the top of the heating chamber 3. The air outlet of the hot air blower 4 is connected to the inside of the heating chamber 3.

[0046] Overall working principle: First, the operator puts the protective glove sleeve base material onto the limiting cylinder 7. The open design at the top of the limiting cylinder 7 makes it easy to insert the excessively long parts. After the device is started, the conveyor belt 2 starts to run at a constant speed, driving the mounting blocks 5 set at intervals on it to move synchronously. The turntable 6 on the top of the mounting block 5 and the limiting cylinder 7 move together with the mounting block 5 along the conveying direction of the conveyor belt 2.

[0047] When the mounting block 5 moves to the side of the first set of sliders 10 on one side of the frame 1, the mounting block 5 contacts the trapezoidal guide block 16 on the side wall of the slider 10. The plane of the mounting block 5 and the trapezoidal guide block 16 are in contact. As the conveyor belt 2 continues to drive the mounting block 5 to move, the mounting block 5 pushes the trapezoidal guide block 16 and the slider 10 to slide synchronously along the slide rail 9. At this time, the slider 10 stretches the second spring 20, and the first spring 17 is in a naturally extended state, ensuring that the trapezoidal guide block 16 and the mounting block 5 are in close contact.

[0048] At the same time, the side plate 8 on the other side of the frame 1 contacts the turntable 6. The rubber pad layer on the side of the side plate 8 near the turntable 6 interacts with the anti-slip coating on the surface of the turntable 6 to generate sufficient friction. As the mounting block 5 moves the turntable 6, the friction drives the turntable 6 to rotate around the top of the mounting block 5, thereby driving the limit cylinder 7 and the protective glove sleeve substrate to rotate synchronously.

[0049] When the slider 10 moves with the mounting block 5, the sprayer 14, which is electrically connected to the limit switch 23, starts. The first nozzle 13 on the top of the slider 10 sprays the first layer of shielding material onto the rotating protective glove sleeve substrate. As the substrate continues to rotate and the nozzle 13 moves synchronously with the substrate, uniform spraying without dead angles is achieved.

[0050] After the spraying is completed, the mounting block 5 continues to move the substrate. The fixed column 18 contacts the guide surface of the trapezoidal guide block 16, squeezing the trapezoidal guide block 16 into the interior of the slide groove 15. The trapezoidal guide block 16 is separated from the mounting block 5. At the same time, the limit switch 23 at the end of the slide rail 9 is touched to turn off the sprayer 14, and the nozzle 13 stops spraying. The spring 20 pulls the slider 10 back along the slide rail 9 under its own tension. The damper 21 plays a buffering role to prevent the slider 10 from hitting the end plate 19 when it resets. After the slider 10 resets, it touches another limit switch 23 to turn on, and the nozzle 13 starts another cycle of spraying.

[0051] Subsequently, the substrate enters the heating chamber 3 at one end of the frame 1 along the conveyor belt 2. The hot air blower 4 at the top of the heating chamber 3 is started to introduce hot air into the heating chamber 3 to pre-cur and shape the first layer of shielding material, remove moisture and air bubbles in the coating, and ensure that the first layer of shielding layer is firmly bonded to the substrate.

[0052] After pre-curing, the substrate moves with the conveyor belt 2 to the side of the second set of sliders 10 and repeats the above-mentioned follow-up, rotation and spraying process. The second nozzle 13 sprays the second layer of shielding material onto the substrate. After spraying, the substrate enters the heating chamber 3 at the other end of the frame 1 for secondary pre-curing, so that the two shielding layers are tightly bonded.

[0053] Finally, the protective glove sleeve with double shielding layer composite is moved to the end of the frame 1 by the conveyor belt 2. The symmetrically arranged peeling plate 22 contacts the limiting cylinder 7. The peeling plate 22 guides the protective glove sleeve to detach from the limiting cylinder 7 with the arc transition surface of the limiting cylinder 7, realizing automatic demolding and completing the entire double shielding layer composite processing process.

[0054] Example 2

[0055] The solution in Example 1 will be further described below with reference to its specific working method.

[0056] In this embodiment, the guide surface of the trapezoidal guide block 16 is inclined and faces the movement direction of the mounting block 5. The contact surface between the trapezoidal guide block 16 and the mounting block 5 is a plane. When the mounting block 5 moves to contact the trapezoidal guide block 16, it can push the slider 10 to move synchronously along the slide rail 9.

[0057] Local working principle: When the mounting block 5 moves with the conveyor belt 2 towards the slider 10, the mounting block 5 comes into contact with the plane of the trapezoidal guide block 16. As the mounting block 5 continues to move, it generates a horizontal thrust on the trapezoidal guide block 16. The thrust of the mounting block 5 is transmitted to the slider 10 through the trapezoidal guide block 16, causing the slider 10 to move synchronously along the slide rail 9, ensuring that the relative position of the nozzle 13 and the protective glove sleeve substrate remains stable, thus realizing follow-up spraying.

[0058] In this embodiment, the second spring 20 is always in a stretched state, the cylinder of the damper 21 is fixedly connected to the end plate 19, and the piston rod of the damper 21 is in contact with the slider 10.

[0059] Local working principle: When the slider 10 moves with the mounting block 5, it will stretch the spring 20. The spring 20 will generate a reverse pulling force. When the mounting block 5 is separated from the slider 10, the reverse pulling force of the spring 20 will drive the slider 10 to reset along the slide rail 9 towards the end plate 19. The damper 21 plays a buffering and deceleration role to prevent the slider 10 from having a rigid collision with the end plate 19, ensuring that the slider 10 is smoothly reset to the initial position, in preparation for the next spraying.

[0060] In this embodiment, the lifting mechanism 11 includes a vertical groove 1101 opened on the top of the slider 10, a support rod 1102 is vertically slidably arranged inside the vertical groove 1101, a positioning bolt 1103 is threaded through the side wall of the slider 10, and the positioning bolt 1103 abuts against the support rod 1102, and the translation mechanism 12 is arranged on the top of the support rod 1102.

[0061] Local working principle: When it is necessary to adjust the spraying height of the nozzle 13, loosen the positioning bolt 1103, and the positioning bolt 1103 separates from the support rod 1102. At this time, the support rod 1102 can be slid up and down along the vertical groove 1101. The support rod 1102 drives the top translation mechanism 12 and the nozzle 13 to rise and fall synchronously until the desired height is reached. Then tighten the positioning bolt 1103, and the positioning bolt 1103 presses against the support rod 1102. The position of the support rod 1102 in the vertical groove 1101 is fixed by friction, so as to achieve precise adjustment of the height of the nozzle 13 and adapt to protective glove sleeve substrates of different lengths.

[0062] In this embodiment, the translation mechanism 12 includes a horizontal plate 1201 fixed to the top of the support rod 1102. A guide groove 1202 is provided on the top of the horizontal plate 1201. A guide block 1203 is slidably connected in the guide groove 1202. A screw 1204 is rotatably passed through the horizontal plate 1201. The screw 1204 is threadedly connected to the guide block 1203. An adjustment knob 1205 is fixed at one end of the screw 1204. A fixing plate 1206 is fixed on the top of the guide block 1203. The nozzle 13 is fixed on the fixing plate 1206.

[0063] Local working principle: When it is necessary to adjust the lateral spraying width of the nozzle 13, rotate the adjustment knob 1205. The adjustment knob 1205 drives the screw 1204 to rotate around its own axis. Since the screw 1204 is threadedly connected to the guide block 1203, and the guide block 1203 is restricted from rotating by the guide groove 1202, the rotation of the screw 1204 is converted into the lateral sliding of the guide block 1203 along the guide groove 1202. The guide block 1203 drives the fixing plate 1206 and the nozzle 13 to move laterally synchronously until the desired lateral position is adjusted, so as to realize the flexible adjustment of the spraying width.

[0064] In this embodiment, there are two nozzles 13, which correspond to the two layers of shielding material of the double shielding layer. The two nozzles 13 are connected to the spraying machine 14, and the spraying direction of the two nozzles 13 is towards the limiting cylinder 7.

[0065] Local working principle: Two spraying machines 14 respectively transport different shielding materials to ensure that the two layers of spraying are carried out independently and continuously, thus ensuring the composite quality of the double shielding layers.

[0066] In this embodiment, a rubber pad layer is provided on the side of the side plate 8 near the turntable 6, and an anti-slip coating is provided on the surface of the turntable 6.

[0067] Local working principle: When the mounting block 5 drives the turntable 6 to move with the conveyor belt 2, the turntable 6 contacts the rubber pad on the side plate 8. The anti-slip coating on the surface of the rubber pad and the turntable 6 increases the friction between them. Since the side plate 8 is fixed, under the action of friction, the turntable 6 rotates around the rotation axis at the top of the mounting block 5, thereby driving the limiting cylinder 7 and the protective glove sleeve substrate sleeved on it to rotate synchronously, so that the shielding material sprayed by the nozzle 13 can evenly cover the entire curved surface of the substrate, avoiding the problem of spraying dead corners or uneven thickness.

[0068] In this embodiment, limit switches 23 are provided at both ends of the slide rail 9. The limit switches 23 are electrically connected to the sprayer 14 and are used to control the start and stop of the spray head 13.

[0069] Local working principle: When the substrate is finished being sprayed, the slider 10 moves with the mounting block 5 to trigger the limit switch 23, turning off the sprayer 14 and avoiding material waste during the reset process. After the reset, the slider 10 triggers another limit switch 23 to turn on the sprayer 14 and start another cycle of spraying. No manual intervention is required, which improves the automation and consistency of the process.

[0070] In this embodiment, peeling plates 22 are symmetrically provided at the end of the frame 1, and the peeling plates 22 are inclined toward the moving direction of the limiting cylinder 7. The distance between the two sets of peeling plates 22 is the same as the outer diameter of the limiting cylinder 7.

[0071] Local working principle: When the protective glove sleeve, which has completed the double shielding layer composite and pre-curing, moves to the peeling plate 22 along with the conveyor belt 2, the limiting cylinder 7 drives the protective glove sleeve into the space between the two sets of peeling plates 22. Since the peeling plate 22 is set at an angle and fixed, as the conveyor belt 2 continues to drive the limiting cylinder 7 to move, the peeling plate 22 generates a reverse frictional force and supporting force on the protective glove sleeve, gradually peeling the protective glove sleeve off the limiting cylinder 7.

[0072] In this embodiment, the peeling plate 22 has an arc-shaped transition surface on the side facing the limiting cylinder 7, and the top of the limiting cylinder 7 is an open design.

[0073] Local working principle: The arc-shaped transition surface can guide the limiting cylinder 7 to ensure that the limiting cylinder 7 enters stably between the peeling plates 22. The open design at the top of the limiting cylinder 7 can easily hide the excessively long parts of the glove sleeve that are not sprayed.

[0074] Example 3

[0075] The solutions in Embodiment 1 and Embodiment 2 will be further described below with reference to their specific working methods.

[0076] Before starting, loosen the positioning bolt 1103 through the lifting mechanism 11 and adjust the height of the nozzle 13 by sliding the support rod 1102; rotate the adjustment knob 1205 of the translation mechanism 12 to drive the guide block 1203 to slide laterally, calibrate the lateral spraying width of the nozzle 13, and adapt it to the specifications of the substrate to be processed.

[0077] The protective glove sleeve substrate is fitted onto the limiting cylinder 7. After the device is started, the conveyor belt 2 drives the mounting block 5, the turntable 6 and the substrate to move at a uniform speed. When the mounting block 5 reaches the first spraying station, it fits with the trapezoidal guide block 16 of the slider 10, pushing the slider 10 to follow along the slide rail 9. At the same time, the side plate 8 contacts the turntable 6, and the friction generated by the rubber pad and the anti-slip coating drives the turntable 6 to rotate, causing the substrate to rotate synchronously.

[0078] Slider 10 triggers limit switch 23, and sprayer 14 starts. The first nozzle 13 completes the first layer of shielding material without dead angles. Mounting block 5 continues to move to fixed post 18, squeezing trapezoidal guide block 16 to retract into slide groove 15. Slider 10 is reset under the tension of spring 20 and the buffering effect of damper 21. Limit switch 23 shuts off sprayer 14.

[0079] The substrate enters the first heating chamber 3 along with the conveyor belt 2, and the hot air blower 4 introduces hot air to complete the pre-curing; then it arrives at the second spraying station, repeats the follow-up, rotation and spraying process, the second nozzle 13 completes the spraying of the second layer of shielding material, and then undergoes a second pre-curing in the second heating chamber 3.

[0080] Finally, the substrate moves to the end of the frame 1, and the inclined peeling plate 22 contacts the substrate through the arc transition surface, achieving automatic demolding under the traction of the conveyor belt 2. After demolding, the limiting cylinder 7 circulates back to the initial position with the conveyor belt 2, ready for the next round of material feeding. The entire process relies on pure mechanical linkage, without the need for complex electrical control, thus balancing efficiency and consistency.

[0081] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
